Patients undergoing Bariatric Surgery at the University of California Davis Medical Center will be divided into two groups, one receiving Standard of Care pain control medications vs the second group which will receive non-narcotic pain medications with rescue pain medications available if needed


Pain control after weight loss surgery is challenging due to the alteration of digestive system anatomy and limitation on using medications which can either be crushed or in liquid form for the first 10 days to 14 days after surgery. Additionally there are multiple programs in place to eliminate the use of narcotic/opioid based pain medications due their potential addictive risks. This study compares two groups of patients whom will have Roux en Y Gastric Bypass Surgery at UC Davis Medical Center, the control group will receive standard of care pain control medications (including opioid based medications) compared to the research arm, this group will receive Gabapentinin and Tylenol for pain control after surgery with rescue pain medications available if needed. Post surgery both groups will be managed by the Bariatric Surgery Team and will be contacted periodically as part of the standard of care to monitor pain control and usage of any rescue medications (if needed).
